章丘市黄露泉崩塌地质灾害及防治对策

Geological Hazards of Huangluquan Collapse and Its Prevention Countermeasures in Zhangqiu City

摘要:

章丘市黄露泉崩塌体是一岩性为奥陶系马家沟组的灰岩体,为一典型的危岩体。危岩体相对高度大于60 m,体积约0.6×104m3,坡度近90°,岩体节理裂隙发育,现东侧已发育成较明显的裂缝,存在岩体崩塌的隐患。20世纪90年代,该危岩体的西南侧,因自然因素曾发生过一次岩体崩塌事件,造成一户民房毁坏。调查表明,该危岩体是由于地质构造作用而使山体隆起,又经多年风化剥蚀作用形成的一个崩塌隐患点。对这样一个危岩体,应当积极开展防治,以使当地居民免受崩塌地质灾害的危害。

Abstract:

Huangluquan collapse in Zhangqiu city is limestone occurring in Majiagou formation of Ordovician group.It is a typical dangerous rock.Its relative height is over 60m,square is 0.6×10~4m~3,and gradient is neraly 90°.Joint fissure developed well in this area,and an evident fissure has been developed in its east part,which will cause danger of rock collaspe.It is proved that,this dangerous rock was formed by uplift due to geological structure function,then experienced long-time weathing and denudation.Counterm...
